First, expand the bracket
2.1s + 2.8 - 1.1s = 7.9
Next, collect like terms
s + 2.8 = 7.9
Lastly subtract 2.8 from 7.9 to get your answer.
s = 5.1
(Hope this helps! ^^)
Answer:
[tex]\boxed {s = 5.1}[/tex]
Step-by-step explanation:
Solve for the value of [tex]s[/tex]:
[tex]0.7(3s + 4) - 1.1s = 7.9[/tex]
-Use Distributive Property:
[tex]0.7(3s + 4) - 1.1s = 7.9[/tex]
[tex]2.1s + 2.8 - 1.1s = 7.9[/tex]
-Combine like terms:
[tex]2.1s + 2.8 - 1.1s = 7.9[/tex]
[tex]s + 2.8 = 7.9[/tex]
-Subtract [tex]2.8[/tex] to both sides:
[tex]s + 2.8 - 2.8 = 7.9 - 2.8[/tex]
[tex]\boxed {s = 5.1}[/tex]
So, the value of [tex]x[/tex] is [tex]5.1[/tex].

if x^2-x-6 and x^2+3x-18 hacpve a common factor (x-a) then find the value of a.
Answer:
a = 3
Step-by-step explanation:
Factor both expressions
x² - x - 6
Consider the factors of the constant term (- 6) which sum to give the coefficient of the x- term (- 1)
The factors are - 3 and + 2 , since
- 3 × 2 = - 6 and - 3 + 2 = - 1 , thus
x² - x - 6 = (x - 3)(x + 2)
-----------------------------------
x² + 3x - 18
consider factors of constant term (- 18) which sum to give the coefficient of the x- term (+ 3)
The factors are + 6 and - 3 , since
6 × - 3 = - 18 and 6 - 3 = + 3 , thus
x² + 3x - 18 = (x + 6)(x - 3)
Both expressions have a common factor of (x - 3)
Compare with (x - a ), then a = 3

what is the constant in the expression 13x3+x2-4x+8
Answer:8
Step-by-step explanation:
it is the only one without a variable.
Answer:
[tex]\boxed {\tt 8}[/tex]
Step-by-step explanation:
A constant is a term without a variable.
Let's analyze each term of the expression: 13x³+x²-4x+8
13x³: this has a variable of x³
x²: this has a variable of x²
-4x: this has a variable of x
8: this has no variable
Since 8 is the term without a variable, 8 is the constant.

Answer:
k = 45*
2k = 90*
Step-by-step explanation:
K will be the same as the 45* degrees, as it is across from it.
2k is twice k, which is 90*.
45* + 45* + 90* = 180*

Laura spent 78.5% of her paycheck on her mortgage payment. If her paycheck was $1562 how much was her mortgage?
Answer:
$337.12
Step-by-step explanation:
Multiply $1562 by 78.5% (or 0.785) =1230.88
Then subtract the percent of her paycheck spent (1230.88) from the total of her paycheck(1562) to find out how much is missing(the mortgage payment)
1562-1230.88=337.12
identify the domain and the range of the function
So the first graph is Radical/Irrational Graph and the second is Parabola/Quadratic Graph.
You can find the domain by looking at the x-axis and for the range, look at the y-axis. That means all of x-axis is the domain and all of y-axis is the range.
From the first graph, the domain is from -2 to +infinite. But because there's a colored dot, it's either ≥ or ≤.
But because -2 is less than + infinite, we use ≤ instead. Thus, x ≥ -2
Remember that x-values can't be equal to infinite. So we use < instead since there's no x-values that are equal to ∞.
Or we can write in interval notation as [-2,+∞) for symbol "[ or ]" is equal to ≤ or ≥ and ") or (" is equal to > or <
Again, the domain for the first graph is x ≥ -2 or x ∈ [-2, +∞)
And the range, look at the y-axis. Because we can substitute x from -2 to less than ∞, that means the range is from -1 because when x = -2 then x = -1 to + infinite.
Therefore, the range is y ≥ -1 or y ∈ [-1, +∞)
Now for the second graph. Look at the x-axis to find the domain. We notice that the colored dot is at x = -3 and the one with white dot is at x =2. The one without the color or white dot is > or < while the colored one is ≥ or ≤.
So the domain is -3 ≤ x < 2 or x ∈ [-3, 2)
For range, look at the y-axis. Notice that the colored dot is at y = -5 and the maximum point is at y =4. The y =4 is still in the domain so the range still applies to the maximum point.
Therefore the range is -5 ≤ y ≤ 4 or y ∈ [-5, 4]

Lines AB and CD are straight lines. Find x and y. Give reasons to justify your solutions.
x= 90° - 63° = 27° (NO perpendicular to AOB)
angle DOB = (90°+90°) -128° (angles on a straight line)
= 180° - 128°
= 52°
y= 180° - x - 63° - angle DOB (angles on a straight line)
=180° - 27° - 63° - 52°
= 38°

9. Given f(x) and g(x), find f(g(3))
f(x) = x2 +9
g(x) = x - 7
O A) -13
O B) 25
O C) 11
OD) 2
=============================================
Work Shown:
g(x) = x-7
g(3) = 3-7 .... replace every x with 3
g(3) = -4
f(g(3)) = f(-4) .... replace g(3) with -4
f(x) = x^2+9
f(-4) = (-4)^2+9
f(-4) = 16+9
f(-4) = 25
f(g(3)) = 25
-------------------------
Another approach:
f(x) = x^2 + 9
f( g(x) ) = ( g(x) )^2 + 9 ... replace every x with g(x)
f( g(x) ) = ( x-7 )^2 + 9 ... plug in g(x) = x-7
f( g(3) ) = ( 3-7 )^2 + 9 .... plug in x = 3
f( g(3) ) = ( -4 )^2 + 9
f( g(3) ) = 16 + 9
f( g(3) ) = 25

A fireplace arch is to be constructed in form of a semiellipse. The opening is to have a height of 2 feet at the center and a width of 6 feet along the base. The contractor cuts a string of a certain length and nails each end of the string along the base in order to sketch the outline of the semiellipse.
1. What is the total length of the string?
2. How far from the center should the string be nailed into the base?
Answer:
The total length of the string is 7.85 feet and the center should be 2.236 feet far the string be nailed into the base
Step-by-step explanation:
Circumference of ellipse = [tex]\pi(a+b)[/tex]
Circumference of semi-ellipse = [tex]\frac{\pi(a+b)}{2}[/tex]
we are given that The opening is to have a height of 2 feet at the center and a width of 6 feet along the base.
So, [tex]a = \frac{6}{2}=3 , b = 2[/tex]
Circumference of semi-ellipse =[tex]\frac{3.14(3+2)}{2}=7.85 feet[/tex]
Distance from center =[tex]\sqrt{a^2-b^2}=\sqrt{3^2-2^2}=2.236 feet[/tex]
Hence the total length of the string is 7.85 feet and the center should be 2.236 feet far the string be nailed into the base

Which equation can be used to graph the line that passes through (6, 15) and is perpendicular to the graph of y-7=1/2(x+2)
Answer:
y = -2x + 27
Step-by-step explanation:
Firstly, we shall need to reform the given line equation;
y-7 = 1/2 ( x + 2)
y - 7 = x/2 + 1
y = x/2 + 1 + 8
y = x/2 + 8
Comparing this with y = mx + c
where m is the slope, then the slope of the line is 1/2
Since the line we are looking for has a slope perpendicular to this line, it means that the product of their slopes is -1
m1 * m2 = -1
1/2 * m2 = -1
m2 = -2
So we want an equation with slope -2 passing through (6,15)
we use the point slope method here;
y-y1 = m(x-x1)
y-15 = -2(x-6)
y-15 = -2x + 12
y= -2x + 12 + 15
y = -2x + 27
